3-Piece Amplified
Speaker System
All PC sound cards have audio outputs. Typically, the outputs will be
marked as “front output” and “rear output.” In some cases, slightly
different terminology may be used. The sound card’s documentation
should help you determine which outputs to use with your speaker system.
1. Connect the cable with the lime green 3.5 mm stereo plug, connected
to the right satellite, into your sound card to the input labeled
“FRONT,” which is also lime green in color.

right satellite.
• Manual
5. Insert the lime green plug on this cable into the lime green jack on the
AAC1 Y-adapter cable.
All stereo-encoded information is heard through the satellite speakers.
The subwoofer contains no stereo imaging, and its sound is nondirectional. As a result, the subwoofer doesn’t have to be placed in any
particular relationship to the satellites. However, placing the
subwoofer on the floor close to a wall or in a corner provides better
bass efficiency and optimum sound.
The answers to most setup and performance questions can be found in
the Troubleshooting guide. You can also consult the FAQs in the
customer support section of our Web site at If
you still can’t find the information you need, please call our customer
service team for assistance before returning the speakers to your
retailer under their return policy.
Warning: The subwoofer is not magnetically shielded. Therefore, it
SHOULD always be placed at least 2 feet (0.6m) from TVs, computer
monitors, computer hard drives or any other magnetic media (e.g.
floppy disks, Zip disks, computer or audio tapes, etc.).
1. Locate the lime green 3.5 mm stereo plug, which is connected to the
right satellite.

To use headphones with the system, plug them into the labeled
jack on the front of the right satellite. When headphones are
connected, both satellites and the subwoofer are muted.
Arrange the satellites to suit your listening tastes—from directly next
to the monitor to as far apart as the speaker cords allow.

Note: The satellite speakers ARE magnetically shielded and can be
placed close to video displays such as TVs and computer monitors
without distorting the image.
Powering On
1. After all other connections are made, plug the power cord, located
on the rear of the subwoofer, into an AC wall socket. The speaker
system is now ready to operate.
Making Connections
Designed and engineered in the USA and manufactured in our ISO9002
certified factory. United States Patents 4429181 and 4625328 plus other
patents pending.
2. Turn on the audio source.
3. Turn on the Altec Lansing 221 speaker system by pushing the power
button located on the front of the right satellite
. A green LED will
light next to the button when the power is ON.
Do not insert the speaker system’s power plug into an AC outlet until
all connections are made. Also, turn off audio sources (i.e., your PC,
MP3 player, console game, etc.) before connecting their outputs to the
221’s inputs.
Note: To avoid hearing a popping sound when you turn on your Altec
Lansing speaker system, always turn on your audio source first.
To ensure first-time operation as expected, please carefully follow the
connection sequences described below in the order indicated.
The knob on the front of the right satellite is the master volume
control for the speaker system. Turn the knob clockwise to increase the
volume and counter-clockwise to decrease the volume.
The satellites are connected together. To set-up the 221 system, insert the
orange DIN connector, connected to the right satellite, into the input
marked RIGHT SPEAKER on the rear of the subwoofer. Then, plug the lime
green audio input plug, which is connected to the right satellite, into the
audio device’s output.
For easy insertion of the DIN connector, notice that the arrow on the
connector must face up.
Various connection schemes between your audio source and the 221
are available. Determine if you’ll be setting up the speaker system for
PC audio/PC gaming, DVD playback, console gaming or with portable
audio devices (such as MP3 or portable CD players), then skip to the
section with that title.

Volume is set too low.
Turn the volume knob clockwise to raise the volume.
Check volume level on the computer sound card or alternate audio source
device, and set at mid-level.
Audio cable isn’t connected to audio source.
Connect audio cable to the audio source. Make sure the signal cable is
inserted firmly into the correct jack.
Audio cable is connected to wrong output on audio source.
Make sure the lime green 3.5 mm stereo cable is connected and fully inserted
into the “line-out” or “audio-out” jack on your soundcard or other audio source.
Problem with audio source.
Test the speakers on another audio source by removing the lime green 3.5mm
stereo cable from the audio source and connecting it to the "line-out" or
headphone jack of a different audio source (e.g., Walkman, Discman or FM radio).
Bad connection.
Check all cables. Make sure they are connected to “line-out” or “audio-out” jack on
your sound card or other audio source—and NOT “speaker-out.”
Volume control in Windows is set too high.
Check the Windows volume control and decrease if necessary.
A problem with your audio source.
Unplug the lime green 3.5 mm stereo cable from the audio source. Then plug it into the
headphone jack of an alternate source (e.g., portable CD, cassette player or FM radio).
Volume level set too high.
Decrease volume level.
Windows volume control is set too high.
Adjust the Windows volume and balance controls to the center as a starting point,
then use the speaker controller to adjust as necessary.
Sound source is distorted.
.WAV and .MID files are often of poor quality; therefore distortion and noise
are easily noticed with high-powered speakers. Try a different audio source
such as a music CD.
Too close to a radio tower.
Move your speakers to see if the interference goes away. If not, you may be
able to purchase a shielded stereo cable from your local electronics store.
Low hum from
The AC in your house is at 60 cycles per second, which
is within the audio frequency of your subwoofer.
Some low hum may be detected when your speaker system is powered on without
an audio source playing, or when the volume is set at an extremely low level.
Loud hum from
Bad connection.
Unplug the power cord from the surge protector (if used), and plug directly
into an AC wall outlet.
Crackling sound
from speakers.
Sound is
Move your cables. Check to ensure they are making a clear connection.
Not enough bass
from subwoofer.
Volume on your audio source set too high.
Lower the volume or bass level on your computer, portable audio device, etc.
Check the volume on audio source.
Increase the volume on the audio source.
Bad connection.
Check to make sure all cables are connected properly and are making a clear connection.
Subwoofer too close to monitor.
Because the subwoofer is not magnetically shielded, it can cause distortion if it’s too
close to your monitor. Move the subwoofer so it’s at least 2 feet from your monitor.
